I have a situation where The user selects from a combobox and based on what they select it sends and receives data via a web service and populates another combo box. There is also a clear button that will clear all of the previous combo box selections, laving the fist combo box with with the original list of choices. If the user goes to select, on the first combo box, the same selection as previously, it does not send it through the web service as the system (flex) already thinks it has done that. Is there a way to clear the cache or force the web service to resend?
